\title{
Do taxa form a monophyletic clade
}
\description{
Check whether or not a set of taxa (existing withing \code{taxasets()}) together form a monophyletic clade.
}
\usage{
areTaxaMono(x, taxindex)
}
%- maybe also 'usage' for other objects documented here.
\arguments{
  \item{x}{
A brownie object
}
  \item{taxindex}{
The column index of the taxaset to be checked
}
}
\details{
Use the command \code{taxasets(x)} to see which taxasets are available for checking.  If the \code{taxindex} entered is greater than the number of taxasets then this command simply returns false and a warning.  The \code{taxasets(x)} command can also be assigned to in order to create new taxasets.
}
\value{
True if the taxa form a monophyly, false otherwise.
